The fridge needs a continuous 12V DC power supply......for 120V AC, propane & DC operation.
No panel lights....no DC power.
On back of fridge lower left area next to the 120V AC cord is were DC + and - leads plug in. Check that you have 12V DC at those leads.
IF no 12V DC......check for blown fuse in DC Dist. Panel
IF yes 12V DC....unplug 120V AC cord and the 12V DC leads (mark them so that you don't reverse the leads when you plug back in!!)
Remove module cover and check the 3A fuse...that is for the DC control circuit (5a fuse is for AC element...35A fuse is for DC element)
Got to have 12 DC before anything will work
